I uninstalled Steam a while ago and don't miss it at all. As soon as I found GOG.com it was game over for Steam. I bought a couple of old games on Steam and they were broken as shit and wouldn't work on a modern PC without lots of frustrating fan-made workarounds, fixed exe files and all that. GOG updated their games almost overnight to make sure they all worked on Windows 10 and that kind of thing goes a long way for me.

That said, the Steam sales are always a great way to get some awesome games on the cheap.
